When test support code relies on production code, a diamond can occur. If this occurs across packages, it can lead to duplicated symbols and incorrect behavior at runtime despite no warnings at build time. This only occurs in Xcode and top-level application testing. This doesn't occur when the code being tested is in a separate package. I'm trying to understand how to correctly manage shared test support code which needs to access production code, or if this is the correct way and it is an Xcode bug. For a minimized example project, see https://github.com/rnapier/SupportCode. The setup includes three packages: Dependencies, which manages all the dependencies for the app and tests; Core which contains core logic and test support; and Feature, which relies on Core an contains feature-related logic and test support. Building this system causes Core.framework to show up three times in DerivedData: ./App.app/PlugIns/AppTests.xctest/Frameworks/Core_59974D35D_PackageProduct.framework ./App.app/Frameworks/Core_59974D35D_PackageProduct.framework ./PackageFrameworks/Core_59974D35D_PackageProduct.framework When unit tests are run, there is a collision on the symbol for Keychain: objc[48914]: Class _TtC8Keychain8Keychain is implemented in both /Users/ornapier/Library/Developer/Xcode/DerivedData/App-grdjljgevqofhqgflgtrqvhvbtej/Build/Products/Debug-iphonesimulator/PackageFrameworks/Core_59974D35D_PackageProduct.framework/Core_59974D35D_PackageProduct (0x100a98118) and /Users/ornapier/Library/Developer/CoreSimulator/Devices/216C441E-4AE5-45EC-8E52-FA42D8562365/data/Containers/Bundle/Application/7197F2F2-EB26-42FF-B7DB-67116159897D/App.app/PlugIns/AppTests.xctest/AppTests (0x1011002c0). One of the two will be used. Which one is undefined. This is not a benign warning. There are two distinct copies of _TtC8Keychain8Keychain and test cases will access one and the app will access a different one. This leads to mismatches when accessing static instances such as .shared. I believe this dependency graph should work, and it does work as long as the top-level testing system is a Swift module. But if it is the application, it builds successfully, but behaves incorrectly in subtle ways.

I enrolled to the apple developer account more than one week ago. Nothing! After 3 or 4 emails to support I received an email with steps I should perform from the iPhone app. I did so, my money was charged and ... nothing. My enrollment has been withdrawn no activation nothing. I made another request (although I am not sure that it is ok). Can somebody help me?

I'm pretty new on this platform and also developing IOS mobile apps. I've been struggling for using the data of the api weather kit apple. I have an acount of apple developer, downloaded the certificate... i follow all the necessaries steps in the portal and also in my project and i keep having this error message when i try to use it. I don't know what else should i do for having working it. I would absolutely appreciate that someone could help me with this. Thank you very much!!!!! Encountered an error when fetching weather data subset; location=<+41.38268070,+2.17702390> +/- 0.00m (speed -1.00 mps / course -1.00) @ 2/3/25, 22:54:03 Central European Standard Time, error=WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors 2 Error Domain=WeatherDaemon.WDSJWTAuthenticatorServiceListener.Errors Code=2 "(null)"

My app has a Watch app companion, and a Widget. are this settings correct to distribute these to TestFlight and Apple Store ?

When trying to use the watchOS preview the simulator fails to load and throws about 15 errors. Clearly the simulator is trying to load all of the iOS packages to the watchOS simulator. However, these packages clearly aren't included in the watchOS app. Furthermore, both apps build successfully to the main simulators, just not the previews. Having a list of errors that simply should not be there is a pretty big annoyance when something is going wrong. How do I fix this?

I paid for an Apple Developer membership, but can only sign 3 apps and restricted to 7 day certificates. I don't even seem to have a way to verify if I am in fact enrolled in the developer program despite being charged for it

Hello, I logged in to my Developer Account and I can't access my Program Resources - img 1 Even if I try to re-enroll, it doesnt allow me as I'm already enrolled - img 2 I have just emailed support and phone support is only available on weeks days. I need to access my certificates asap to fix a push notification issue. Any suggestions?

The WatchOS developer is not allowed to obtain healthKit permission status. The result is always unauthorized (either by clicking the dot/cross in the upper left corner or by turning on all Health, on some, off all). WatchOS 开发获取 healthKit 的权限状态authorizationStatus不准。结果始终都是未授权（无论是点击左上角的点叉号还是开启全部健康项开关，开启部分，关闭所有），怎么处理？

iOS simulator way slower to launch after updating to Xcode Version 16.2 (16C5032a). macOS 15.3.1 (24D70) MacBook Air M1, 8GB

I found this file config in my macOS System Process but I dont understand Who using this service and Who set this up for me? I never use any token

I have this code: var eventIn = kevent(ident: UInt(self.socket), filter: Int16(EVFILT_WRITE), flags: UInt16((EV_ADD | EV_ENABLE)), fflags: 0, data: 0, udata: nil ) I looked at it and thought why do I have those extra parentheses? So I changed it to var eventIn = kevent(ident: UInt(self.socket), filter: Int16(EVFILT_WRITE), flags: UInt16(EV_ADD | EV_ENABLE), // changed line! fflags: 0, data: 0, udata: nil ) and then kevent gave me EBADF. Does this make sense to anyone?

with the latest Xcode version, i am getting all kinds of errors: few main ones: /Users/akashbhatia/MyApp/ios/Pods/Target Support Files/ReactCodegen/ReactCodegen-prefix.pch:2:9 Could not build module 'UIKit' /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator18.4.sdk/System/Library/Frameworks/CFNetwork.framework/Headers/CFNetwork.h:18:10 Could not build module 'CoreFoundation' /Users/akashbhatia/MyApp/ios/Pods/Headers/Public/RCT-Folly/folly/portability/Config.h:20:10 'folly/folly-config.h' file not found I have reinstalled Xcode, removed derived data, installed pod over and over again, but I have realized from the first error here, that it has more to do with Xcode and React Native now. Any help will be appreciated.

I’m having a problem with my Apple Developer subscription payment: 1️⃣ My card was successfully charged €99 – I have a confirmation email from the payment system 2️⃣ But my Apple Developer account shows "Order Canceled" – the cart displays this status Additionally, when I log into my account, it prompts me to register again as if the payment didn’t go through. Questions: How can I restore access to Apple Developer? What should I do about the payment—will it be refunded automatically, or do I need to contact support? Could this be a system error, and should I try paying again? Thanks in advance for your help!

Upon updating to Xcode 16.3, my StoreKit2 unit testing suite encountered a malfunction. let result = await product.purchase() The code snippet above simply halts execution, preventing the task from progressing. In a regular environment, everything appear to function correctly.

I want to statically link xcframework as binaryTarget in Swift Package, but it is copied into the product as dynamic when the Xcode build. How to use xcframework in SwiftPackage and statically link it into iOS product? The Package.swift content and the project are: The WebP.xcframework is static: The Xcode Build Product's WebP.framework is dynamic:

The flags like #if DEBUG ... endif are dependent on the Active Compilation Conditions. So if they say DEBUG the enclosed code block will be executed, otherwise not. Now I have the phenomenon that a #DEBUG block in a Package does not evaluate these conditions. It rather depends on the name of the configuration used to build. So if I build my app with Active Compilation Condition set to DEBUG, but the configuration name is something like App-Release, the DEBUG block in my Package is not added/executed. The ones which are directly in the project are added. Vice versa if the Compilation Condition say RELEASE but the configuration is called App-Debug the blocks in the Package are added to the compilation, but the ones in the project itself are not It suffices that the config name contains the word Debug for this to happen. E.g. the configuration App-Release-Debug (I know that this would be stupid, but it is for demonstrating purposes) will cause the Packages to include the DEBUG blocks. This happens no matter what you set in the Build Settings of the project and/or target. The Packages are added via GitHub/GitLab Source Control with SPM. Any ideas why this behaves like it does? It doesn't seem like it should...

I have been wanting to make a mobileprovision file and a p12 file, how do i make these files but using only ipad?

Until recently, it was possible to view the profiles of every user who posted in the forums. The profile page would then have links to posts/replies and other pages so that one could "follow" the recent comments by those users. However, it appears that it no longer is possible to view a profile of individual "DTS Engineer". What I mean is I can no longer view their profile page and as a result the recent posts/replies that a specific "DTS Engineer" makes. It's especially a loss because posts made by such engineers are very helpful and valuable and not being able to easily follow such posts on a single page makes the forum software less useful. Is there a way the previous feature can be brought back?
